With the introduction of the ISA ADN2, the classic ISA mic pre can be implemented directly on a Dante network, providing console-grade preamps to the most advanced of audio networks. ISA ADN2 is an optional two-channel A-D card that provides high-quality analogue-to-digital conversion for the ISA One mic preamp and DI. Featuring Dante, AES3, ADAT and S/PDIF connectivity, the card operates at sample rates up to 24-bit/192kHz.

The card offers a familiar set of standard professional connectors with primary and secondary RJ45 Dante output ports, an XLR connector for AES3 output, a TOSLINK connector for ADAT output and RCA connector for S/PDIF output. Word Clock I/O on BNC connectors allows synchronisation with many external devices.

Dante outputs on the card provide ISA One with network connectivity to all Focusrite RedNet devices and Red interfaces, as well as any other Dante-enabled device from hundreds of manufacturers. Metering and settings are accessed through RedNet Control, routing is configured using Dante Controller. Both RedNet Control and Dante Controller software are included.
